Im not a big fan of the tapioca pearls that make Boba truly Boba tea. But I went to a place in the SF area last year that had a wide selection of things you could put in your tea (I think there was a place like it on sawtelle in W. LA too)
One of my favorites was to put Chocolate pudding in my tea... but I haven't found another "boba" place that does this.
I split my time all over south western California - Long Beach to OC to SD -- along the coast. I almosy never go into LA proper anymore.
any suggestions along the way?
